It is believed that the many advantages of an artificial silk washing apparatus constructed in accordance with the present invention will'be readily understood, and although a preferred em bodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction and in the combination andjarrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is, claimed is:--- 1. An artificial silk washer of the character del5 scribed comprising a perforated tube adapted to be mounted in a fluid tank, saidtube being ta pered at one end and being provided at the other 5 end with an integral annular plate extending radially outwardly, thereof to provide a supporting flange, and radially inwardly thereof to proll 30 the rayon; and means on the ends of the sleeves for providing leak-proof joints therebetween, said means including packing rings irioiinted on the lower ends of the sleeves, said packing rings being engaged with the perforated tube and resting on the upper ends of the subjacent sleeves.

2. An artificial'silk' washer of the class described comprising a perforated tube adapted to be mounted in a fluid tank, an annular plate fixed on the lower end of said tube and extendmg radially inwardly and outwardly therefrom,

' a discharge neck depending'from the plate, a gasket mounted below the plate and encircling the discharge neck, a plurality of perforated sleeves removably mounted one on top of the otheron v the perforated tube and being greater in diameter than said tube to provide an annular space therebetween, said sleeves constituting removable .holders for the artificial silk, the lowermost sleeve resting on the plate, each sleevehaving its lower 7 end portion formed to provide anJinternalchan-w q nel, resilient packing rings-mounted in the channels and engaged with the perforatedtube, said packing rings further being exposed through the lowermost walls of the channels to be engaged on V the upper ends of the subjacent sleeves; for pro viding leak-proof,jointstherebetween, and a cap detachably mounted on'the upper end ofthe per forated tube and engaged with the uppermost sleeve for removably securing the sleeves in position on the perforated tube.
